Assessment and prediction of coal abrasiveness -

1990-9-1  'Inherent abrasive index' (IAI), defined as the abrasion index of the coal in an air-dry condition, was related to the ash analysis of the coal by the equation: IAI=(S+F-1.11)/0.118 (r=0.98) (1) where S and F are the mass per cent of silicon (as SiO^) and iron (as Fe^C^) respectively in the coal, at 15% Assessment and prediction of coal ...

2008-3-3  This, in turn, suggests that for this suite of rocks the abrasive mineral content may be the principal cause of wear to the tools. The relation between tool consumption (TC) and rock abrasiveness of the Coal Measures Rocks were determined as follows: (4) TC = 0.2533 C A I − 0.0948 ( with R 2 = 0.9853 r = 0.9926).

Coal characteristics that lead to abrasion during grinding

2011-10-18  Results indicated that coal weathering renders coals less abrasive, compared to unweathered coals. It was concluded that AI and HGI are experimentally dependent; excluded and included minerals were equally abrasive; and three-body abrasive wear was established to be the main wear during grinding in an abrasion index tester pot.
